SIXTH QUARTERLY STATUS REPORT ON NONDESTRUCTIVE SYSTEM FOR INSPECTION OF FIBER GLASS REINFORCED PLASTIC MISSILE CASES AND OTHER STRUCTURAL MATERIALS

摘要

A slow-scan television system is being used to produce X-ray images. A standard audio-frequency magnetic tape recorder has been used to record the slow-scan video signal with considerable success. This initial work proves the applicability of using a slow-scan television system in conjunc¬tion with an audio-frequency recorder to provide an economical means of recording television X-ray images.nThe slow-scan equipment requires less radiation quantities to pro¬duce useful images than the standard 525 line, 30 frame per second rate equipment.
